Snow Leopard on DG31PR

[Macpaq]

HI, I had revisited the idea of install Snow Leopard on my DG31PR mobo, the first time I did it was not successful so I put the idea to the back burner, now I am trying to do it again, just like last time I have tried probably every method in insanelyMac without success, I remember in one of ths many posts I read, someone was saying that DG31PR is a easy mobo for SL.. and i also read some posts that people did get it to work with this board , just not me. I have Leopard 10.5.8 running perfectly on this mpbo, Could someone who got this mobo working help me?

My system is DG31Pr Q6600 quad core processor, 4G RAM, nvidia 7300 GT video card, all 4 SATA are used one for DVD drive, two for 500G HD, one 120G for the will be Snow Leopard , on board ethernet znd onboard sound, Every thing works perfectly under 10.5.8 . Thanks in advance.
